HLHUNHU l IUO Patented Dec. 17, 1929 waits a! JERRY I-IBSCHMAN, OF GREATNECK, NEW YORK .AEROPLANE Application led October 27, 1927. Serial No.229,192.

My invention relates to improvements in aeroplanes of the class shown inmy prior United States Patent No. 1,025,063, dated April 80, 1912, inwhich the wings are pivoted to swing forward for rising, or rearward fordescending or inaction, or one forward and the other rearward forturning in either direction.

In my said patent, the wings are shown 1o provided with independenthandles for manipulating them and segmental locking devices for securingthe handles and thus the wings in any position to which they may beadjusted.

My present invention consists of mechanism whereby the wings on oppositesides may be adjusted simultaneously te any required position by asingle control, so as to insure the proper positioning of both wingswith respect to each other in any desired adjustment.

To this end my invention comprises in its entirety a mechanismconnecting the opposite wings by which they are simultaneously andharmoniously adjusted forward or rearward, another connecting mechanismby which one wing is moved forward and the other rearward simultaneouslyand harmoniously, a control and means for engaging the control witheither of the two adjusting mechanisms substantially as hereinafter morefully set forth.

In order that my invention may be fully understood, I shall firstdescribe in detail the mode in which I at present prefer to carry theinvention into practice and then particularly point out the invention inthe claims.

Reference is to be had to the accompanying drawings forming part of thisapplication, in which like parts are designated by the same letters inall the figures.

Figure 1 is a plan view of an aeroplane of the class referred toprovided with wing adjusting mechanism embodying my invention.

Figure 2 is a rear end elevation of the same.

Figures 3, 4, 5, 6, and 7 show various positions to which the wings ofthe said aeroplane may be adjusted.

Figure S is an enlarged detail view of the wing operating mechanism.

In the specific embodiment of my invention shown in the drawings, 8designates the frame of the aeroplane; 9, 10 the vertical 55 posts towhich the wings 11, 12 are pivoted by their respective hubs 13, 14; 15,16 the lower guys, respectively, of the wings 11, 12, and 17, 18, therespective upper guys thereof, all substantially as shown and describedin my prior Patent No. 1,025,063, before referred to.

To adj ust the wings 11, 12, simultaneously and harmoniously to anydesired position by a single control, I in this specific embodiment ofmy invention, fix to the respective pivotal wing hubs 13, 14, bevelgears 19, 20.

The bevel gear 20 is engaged by a bevel gear 21, fixed on a transverseshaft 22, mounted to turn in bearings 23, fixed on the frame of theaeroplane, and on the transverse shaft 22, is fixed a worm wheel 24,which is geared to a worm 25 fixed on a shaft 26.

On the shaft 26 is keyed to slide axially thereon, but turn therewith, aspring pressed T5 wheel control 27, so that when the control 28 isturned the wing 12 may be swung to any of the positions shown in Figures3, 4,

5, 6 or 7, for inaction, rising, straight flying, banllring and turningor descending, respecso tive y.

On the opposite end of the transverse shaft 22 is keyed to slide axiallythereon, but turn therewith, a sleeve 28, on opposite ends of which arefixed bevel gears 29, 30 respective- S5 ly, and a clutch collar 31,engaged by an angle clutch lever 32, the other arm of which is engagedby the axially sliding wheel control 27.

The arrangement and adjustment is such that when the spring pressedwheel control is pressed axially rearward, the bevel gear 29 and not thebevel gear 80, will be engaged with the bevel gear 19 of the wing 11, sothat when the wheel control 27 is turned, the wings 11, 12, will beswung simultaneously and harmoniously, one forward and the otherrearward to any desired position, according to the direction and extentto which the wheel control 27 is turned. 100

When, however, the spring pressed wheel cont-rol is pressed axiallyforward, the bevel gear 3 and not the bevel gear 29, will be engagedwith the bevel gear 19 of the wing 1l, so that when the wheel control 28is turned, the wings 11 and 12, will be swung harmoniously andsimultaneously both forward or both rearward to any desired positionIaccording to the direction and extent to which the wheel control isturned.

The aeroplane can thus be easily steered upward or downward or turned ineither direcy tion by a single control in Convenient reach of the iyeron his seat .33. Owing to the worm gear preferably employed, the wingsare automatically locked in any position to which they may be adjustedso that the flyer can remove his hands temporarily from the controlwheel to use them for other purposes. f, 1t is evident that equivalentmechanism (d may be substituted for the mechanismherein described,without departing from the boundaries of my invention as defined by thefollowing claims.

l claim as my invention:

l. An aeroplane comprising a frame, wings independently pivoted onopposite sides thereof, a wing operating wheel, operating connectionsbetween the wheel androne wing, reversible operating connectionsbetweenv the wheel and the other wing, and means forreversing theconnections between the wheel and the latter wing, so that both wingsImay be moved together forward or backward,.or independently forward orbackward, vor one forward and the other backward.

2. An aeroplane in accord with claiml in which the reversibleconnections between one wing and the wheel comprise a wheel shaft onwhich the wheel slides but with which it turns, a wing operating shaft,gearing connecting the two shafts, reversible gearing between theoperating shaft and t-he one wing, a clutch gear for reversing saidgearing, and operating connections between the clutch Gear and the wheelsliding on the* wheel shaft.

In testimony whereof I aiiiX my signature.

JERRY HBSCHMAN.
